AuthDNS

Our Authoritative DNS (AuthDNS) cluster announces 193.0.9.0/24 and 2001:67c:e0::/48 from AS 197000. The service hosts reverse DNS zones, ripe.net, and provides secondary service for various ccTLDs. The cluster is composed of three core instances located in Amsterdam, London and Stockholm. At each of these sites, a router distributes the DNS queries across multiple servers, running a mix of BIND, Knot DNS and NSD. The capacity of these core sites is supplemented by Hosted DNS instances. These single-server instances run in ISP networks or are connected to Internet Exchanges. If you would like to host such a server, please send us your application.
